JOHN ROBERT IEIROE, OF BUFFALO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 310,847, dated January 13, 1885. Application filed July 19, 1884. (No model.)

To til whom t may concern.-

Be it known that I, J oHN R. Piemon, a citizen ofthe United States, residing at Buffalo, in the county of `Sangamon and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical sectional view of my device. Fig. 2 is a top View of the same. Fig. 3 is a cross-sectional View, and Figs. 4 and 5 are detail views.

This invention has relation to wheel-cultivators; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letters A A designate the plow-beams, to which are attached the plow-standards B and the han'- dles C. Theplow-beams are made long enough lo extend forward of the axle-arch D, and to their front ends are attached the draft clevises or links E. The axle-arch D consists of' the transverse journal-bar F, to which the inner and upper eyes or bearings, c, of the quarter-arms G are connected, so that each quarter-arm has an independent movement of rotation about the horizontal journals oi' said bar F, as indicated. The quarter-arms G are curved downward and outward from the horizontal bearings c, and terminate at their outer ends in vertical bearings b. Said arch further consists of the lateral standards H, the upper ends of which are swiveled in the vertical bearings b of the quarter-arms G. The lowerends of these standards are turned inward to form horizontal arms K, of rectangular form in cross-section, to which are clipped the forward portions of the plow-beams A, the clips being indicated at L.

To the upright portion of each standard H, which is also rectangular in form, is connected an adjustable spindle, N Forthis purpose the spindle is provided with a verticallyextending sleeve or bearing, m, adapted to fit on the upright, and adjustable thereon, to enable the spindle to be placed higher or lower, according to the position of the wheel required by the work. rlhe spindles are secured in position after adjustment by clamping-bolts or other common fastenings.

In rear of the points of attachment of the beams to the arms K of the arch said beams are provided with inclined bearings V, which are secured to the sides of the beams in a strong and rigid manner. Through these bearings extend the supportingbars Z, in inclined position, each bar being held by its middle part in the bearing by means of a screw or bolt, s, which extends through aperforation in said bearing, as shown at c, and through a perforation7 d, in the bar Z. Near the upper endof. this bar is made an aperture, d', and when the plow-beam is raised and the bar Z is pushed downward through the bearing the fastening screw or bolt s is passed through the perforation d, securing the bar in the bearing by its upper end. In this position its lower end, w, rests on the ground, and as it is made with a rounded front edge, t, it passes easily over the ground when the draft is applied, holding the plows in elevated position above the surface. In this Constr Iction the plow-beams are rigidly connected to`- the sides of the arch, and the draft is directlyapplied to their front ends. Each beam is free to move forward with refence to the other, because the sides of the` arch are swiveled in vertical bearings. The horizontal bearings a ofthe quarter-arms and the journal-bar F allow freedom of movement t0 the beams in rising and falling independently of each other.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

l. The cultivator arch consisting of the transverse journal-bar F, the quarter-arms G, having horizontal upper bearings engaging the journals of said bar, and lateral standards H, having horizontal arms at their lower ends,

to which the plow-beams are clipped, and having their upper ends swiveled in the Vertical upper bearings of the quarter-arms, substantially as specified.
